I have a problem with defining boundaru conditions id NDSolve
of PDE
F is function of [x,t]
Conditions has form : (d/dx)F[0,t]==0;
I wrote this in form : D[F[0,t],x]==0
Its TRUE (0==0)
Then i wrote D[F[x,t],x]
out: F(1,0)[x,t] ; {(1,0) looks like "power"}
And "copy"&"paste", and changed x to 0 in arguments
This way works, but I'm sure is a better way ?
